According G.S.B.vol.1, Her full younger sister "Old Coquette", bred by Duke of Bolton about 1722, produced "bay bolton mare4" in 1729. However, written in the same book, "bay bolton mare4" produced "bolton little john" in 1731. Information of either will be wrong.
"bay bolton mare4" was bred by Duke of Bolton, and she was registered chestnut-colored.
